Where to donate locally to help addiction research and support?

Hello Seattleites!

Any ideas where I could donate locally to support addiction services? My father passed away from liver disease (alcoholic) in 2021 and we are finally closing his small estate after way too many years. I would love to make a small ($5k, matched by Microsoft where my husband works) donation to a local organization in his memory. Preferably with no religious affiliation and I’d love if it would support research in particular.

Any ideas would be greatly appreciated!
